Claims7
A tap for dispensing liquids comprising:
- a main body equipped with an integrated tamper-evident ring-seal which can be A removed when opening the tap for a first time;
- a lower body designed to be operatively connected to the main body;
- a flexible valve located between the main body and the lower body and equipped with a central opening with slit consisting of slits or flaps, the flexible valve being designed to cooperate operationally with a dart or pin able to be inserted in the main body, in the flexible valve and in the lower body and able to engage the flexible valve to open or close the slits or flaps;
- and
- a cover cap placed above the main body and designed to protect the tap and to allow heat and aseptic treatments, the cover cap being equipped with a semi-spherical support surface designed to keep the flexible valve in its closed position and avoid opening of the flexible valve due to pressure inside the tap,
- wherein the flexible valve is made of silicone and is formed of an outer fastening ring which has an upper surface and a lower surface, designed to couple respectively with the surface of the body and a lower seat of the lower body, the valve having a valve zone which allows a controlled elongation and of the valve in a vertical direction, the valve also having an anchoring zone designed to mate with a tooth of the lower body, keeping the valve in an extended configuration and generating a sealing force necessary for the flaps of the flexible valve.
